6 Claims.

The present invention relates generally to structures for bulkheads, jetties, groins, sea-walls and the like, and the present invention relates more particularly to such structures made of sheet piling of the laterally interlocking type with some of the piling elements of longer length and heavier weight than others to provide beam strength at given intervals with shorter elements between to form a continuous, uninterrupted barrier for holding soil or sand against shifting.

An advantage of the present invention is that a continuous wall is presented to the moving waters whereby no local disturbances are produced such for example as swirling eddies formed by tidal movement around offset piles employed with structures heretofore used, which eddies scour and carry the soil or sand from those localities resulting in an undermining which soon spreads and extends and leaves a great portion or all of the structure undermined.

Another advantage of the present invention is that a considerable saving is made by having several of the pilings of the structure itself placed at appropriate intervals serve as beams, using lighter material for the intermediary wall.

Other objects and advantages of the present invention will appear from the drawing forming part hereof and from the specication describing illustrative embodiments of the invention and from the claims appended thereto.

In the drawing forming part hereof and somewhat diagrammatically illustrating embodiments of the present invention.

Figure 1 is a diagrammatic elevation View, in part cut away, showing a structure embodying the present invention; and

Figure 2 is a plan view, in part cut away, illustrating a conventional form of interlocking sheet metal piling such as can be used in structures of the present invention.

Figure l somewhat diagrammatically illustrates an embodiment of the present invention in which the bulkhead or seawall structure comprises long and heavier pilings 10, 10 which eX- tend deeply into the stationary, harder penetration material 1l, the intermediate lengthv and lighter pilings, 12, 12 extend to a lesser depth into said harder penetration material l1, and the comparatively short and lighter pilings 13, 13 extend just through the shifting soil or sand 14 and for a short distance into said harder penetration material. A wale or binding bar 15 secures said pilings, 10, 10, 12, 12, and 13, 13 together at their v upper ends by means of the bolts 16, 16. In this 'embodiment of the present invention a gradationis made between the long and heavier pilings 10, 10 which serve as master piles and beams as well as elements in the bulkhead or seawall and the short elements 13, 13 which have their chief function as elements of the bulkhead orV seawallv because they have little or no penetration into the harder penetration material 11. This gradation is by means of the intermediate length pilings 12, l2 which in addition to serving as elements of the bulkhead or seawall serve also to some extent to supplement the long pilings 10, 10 By this gradation there is secured a balance between economy of the structure and the stability thereof.

Figure 2 shows somewhat diagrammatically a plan view of the structures of Figure 1 in which the Wale or binding bar 15, by means of the bolts 16, 16, secures together at their upper ends the pilings, 10, 12, 13, 13 of the seawall or bulkhead structure. This shows one of a number of forms for laterally securing rigidity which are well known in the art.

In Figure 1 there is shown but one embodiment of the present invention and it is to be understood that various arrangements and combinations of longer and heavier, and lighter intermediate shorter piling elements can be assembled to suit various conditions in accordance with the present invention in which a bulkhead or seawall is assembled in units comprising interlocking steel piling elements some of which serve as master piles or beams as well as part of the bulkhead or seawall and others serve sub-- stantially entirely in their capacity as elements of the bulkhead or seawall. A unit can comprise one pair or more pairs of pilings, at least one of which is a master piling, the total number of pilings in a unit being determined by the nature of the soil or sand and the conditions to which they are to be subjected.

In places, where anchoring of the seawall or bulkhead is required, anchoring rods will be secured only to the master piling, by any of the many appropriate means which are well known in the art.

Having thus described my invention what I cla-im and wish toprotect by Letters Patent isl. A wall for preventing shifting of shore sands and soils comprising a plurality of sheet piling of the laterally interlocking type assembled in side by side relation in units comprising a long anchoring element penetrating comparatively deeply in non-shifting material, a plurality 0I" elements of intermediate length penetrating said non-shifting material and a plurality of short sin stl v ido allA
